UNITED vSTATES PATENT OFFICE CLUTCH Charles Raymond Waseige, RueiL-Malmaison, France, assignor, by mesne assignments, to Eclipse Aviation Corporation, East Orange, N. J., a corporation of New Jersey Application September 14, 1932, Serial No. 633,194 In France November 10, 1931 7 Claims. (Cl. 192-113) This invention relates to clutches but more trated in Figs. 1-3 by joining together twodiscs I particularly to clutches of the progressive type and 2; the surface of contact of at least one of such as utilized, for example, in the driving of them being provided with cavities I5. The two compressors for aeroplanes. discs may be assembled for example by electri- 5 'It has been found that the linings of such cally Welding them at points I8 or in any other 6 clutches are rapidly destroyed due to the abnorsuitable manner. mal heat generated by the rubbing or frictional Fig. 4 shows another form that the discs I and contact between the clutch elements during the 2 may take, wherein there is provided on one or periods when the two elements are rotating relaboth discs a series of intersecting grooves.

It ls to be understood that the invention is not 10 It is. the object of this invention to provide to be limited to the particular embodiments inv eifective means whereby the destruction of clutch connection with which it has been described but linings may be precluded, only by the scope of the claims appended hereto.

In order that the invention may be clearly un- What is claimed is: l5 dei-stood, reference is had to the accompanying 1. In a clutch mechanism, a `rotary shaft, a l5 drawing forming a part of this specification and hollow clutch member comprising a central coniin which: c'al section and a peripheral fiat section, the lat- Fig. 1 is a vertical section through the device ter designed to be engaged by friction faces, of this invention. means to introduce a cooling liquid through the Fig. 2 is an elevation-of a constructional form shaft to said conical section and means compris-v 20 of the driving clutch member or disc. ing flutes on said fiat section for withdrawing Fig. 3 is a section at 3 3 on Fig. 2. the liquid from said member.

5. In a. clutch mechanism, a rotary shaft, a second rotary shaft, a hollow disk secured to first of said shafts, friction members on opposite sides of said disk for connecting the disk to the second rotary shaft, means forming an axial liquid passageway through the rst shaft,

means connecting the passageway with the interior of the disk, and said disk comprising two integrally joined members having contiguous peripheral faces, one of which is provided with a series of intersecting grooves extending from the disk periphery to the hollow interior thereof, said grooves constituting conduits for the circulation of liquid` through the disk, a housing connected to the second rotary shaft and enclosing said disk, and said housing having outlet openings therein positioned in the plane of the grooves.

6. In a clutch mechanism, driving and driven members having friction faces thereon, an axial conduit in one member adapted to introduce a cooling medium internally of the member, radial 6 outlet means in the first member and radial outlet conduit means in the second member positioned in the plane of the first mentioned member permitting withdrawal of the medium through thel secondmember, and said radial conduits be- 10 ing extended through the periphery of the second member whereby` the cooling medium passes through both members in a radial direction.

7. In a clutch mechanism, a hollow driving member, a hollow clutch member fixed to the i5 shaft, a second clutch member encompassing the first mentioned member and having friction disks engaging the first member, said hollow member having a passageway through the portion thereof in engagement with the disks, inlet means for 20 introducing a cooling medium to the first member, and outlet means for withdrawing the cooling medium through the second member, said inlet means, said passageway and said outlet means being positioned in the same radial plane. 25
